Abstract

The invention discloses an immune-enhanced feed for Megalobrama amblycephala and a production method for the immune-enhanced feed. The feed mainly comprises fructo-oligosaccharide, a water extract of full honeysuckle and choline in a weight ratio of (0.05-0.2):(1-1.5):(0.1-0.2). The feed ensures that the Megalobrama amblycephala has balanced nutrition, promotes the growth, can strengthen immunocompetence, catching survival rate and transportation resistance and reduce the rotting rate of fish bodies, and can be used for industrialized production, and the cost of the feed is reduced.

Description

technical field [0001] The invention belongs to the technical field of aquatic compound feed, and in particular relates to an immune-enhancing feed for bream and a production method thereof. Background technique [0002] Group head bream (Megalobrama amblycephala), belongs to Cyprinidae, Cyprinidae, Cyprinidae, bream genus. Commonly known as Wuchang fish, group-headed bream or flat-chested bream. The fish was originally produced in Liangzi Lake, Ezhou, Hubei Province in the middle and lower reaches of the Yangtze River. In 1955, Yi Bolu distinguished it from triangular bream morphologically, and identified it as a new species - bream. This fish is one of the important herbivorous economic fishes in my country. Because of its wide feeding habits, high survival rate, easy fishing, short feeding cycle, small head, high meat content, rich nutrition, delicious and tender meat, etc. As an excellent herbivorous fish species, it is widely promoted throughout the country. In 2009, ...
